Top 10 Methods to Save Cost in AWS Cloud
- 1. Right-size EC2 Instances: Regularly analyze and choose the most appropriate instance type and size for your workload. Downsize or terminate unused resources.
- 2. Use Savings Plans & Reserved Instances: Commit to one- or three-year terms for EC2, Lambda, and Fargate to get significant discounts compared to On-Demand pricing.
- 3. Enable Auto Scaling: Scale resources up and down automatically based on demand, avoiding over-provisioning and reducing idle costs.
- 4. Use Spot Instances: Take advantage of spare capacity for up to 90% savings for flexible, interruption-tolerant workloads.
- 5. Clean Up Unused EBS Volumes & Snapshots: Identify and remove unattached EBS volumes, obsolete snapshots, and idle Elastic IPs.
- 6. Store Data in S3 Intelligent-Tiering or Glacier: Automatically move infrequently accessed data to lower-cost storage classes.
- 7. Leverage Cost Explorer & Budgets: Use AWS Cost Explorer, Budgets, and Cost & Usage Reports to monitor spend and receive alerts.
- 8. Optimize Data Transfer: Minimize inter-region and internet data transfer; use CloudFront CDN and locate resources in the same region.
- 9. Use Managed Services: Replace self-managed solutions with managed offerings like RDS, DynamoDB, and Lambda to avoid operational overhead and hidden costs.
- 10. Turn Off Non-Production Resources: Automate shutdowns of dev/test environments during off-hours with Instance Scheduler or Lambda.
